The code N73.9 is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.
Unspecified diagnosis codes like N73.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Pelvic Inflammatory Disease
Also called: PID
Pelvic inflammatory disease (PID) is an infection and inflammation of the uterus, ovaries, and other female reproductive organs. It causes scarring in these organs. This can lead to infertility, ectopic pregnancy, pelvic pain, abscesses, and other serious problems. PID is the most common preventable cause of infertility in the United States.
Gonorrhea and chlamydia, two sexually transmitted diseases, are the most common causes of PID. Other bacteria can also cause it. You are at greater risk if you
- Are sexually active and younger than 25
- Have more than one sex partner
- Douche
Some women have no symptoms. Others have pain in the lower abdomen, fever, smelly vaginal discharge, irregular bleeding, and pain during intercourse or urination. Doctors diagnose PID with a physical exam, lab tests, and imaging tests. Antibiotics can cure PID. Early treatment is important. Waiting too long increases the risk of infertility.
